Electric heating type support, exhaust gas purifying device, method for producing electric heating type support, joined body, and method for producing joined body
The invention provides an electric heating type support which has good joining reliability between a metal terminal and a honeycomb structure, an exhaust gas purifying device, a method for producing the electric heating type support, a joined body, and a method for producing the joined body. The electric heating type support includes: an electrically conductive honeycomb structure including a pillar shaped honeycomb structure portion composed of conductive ceramics, the pillar shaped honeycomb structure portion including: an outer peripheral wall; and porous partition walls disposed on an inner side of the outer peripheral wall, the porous partition walls defining a plurality of cells, each cell penetrating from one end face to other end face to form a flow path; and a pair of metal terminals disposed so as to face each other across a central axis of the pillar shaped honeycomb structure portion, each metal terminal being joined to a surface of the electrically conductive honeycomb structure via a welded portion so as to follow a surface shape of the electrically conductive honeycomb structure.
本发明提供金属端子与蜂窝结构体的接合可靠性良好的电加热型载体、废气净化装置、电加热型载体的制造方法、接合体以及接合体的制造方法。电加热型载体具备导电性的蜂窝结构体和一对金属端子，该导电性的蜂窝结构体具备柱状蜂窝结构部，该柱状蜂窝结构部具有外周壁和多孔质的隔壁，该多孔质的隔壁配设于外周壁的内侧，并区划形成从一个端面贯通至另一个端面而形成流路的多个隔室，且该柱状蜂窝结构部由导电性陶瓷构成，一对金属端子配设成隔着柱状蜂窝结构部的中心轴而对置，并以贴合蜂窝结构体的表面形状的方式借助焊接部位而接合于蜂窝结构体的表面。
